KEY MESSAGES

- Light rain will continue for some through the afternoon, with most being dry by sunset today. Dry weather will remain into the start of the work week.

- Seasonal temperatures will remain through much of the upcoming work week, with comfortable humidity levels. Temperatures and humidity will start to increase late in the week.

- A more active pattern takes shape during the second half of the work week, introducing more chances for showers and storms.

SHORT TERM /THROUGH SUNDAY NIGHT/

Issued at 219 PM CDT Sat Aug 1 2026

Upper low continues to slowly drift east, with the last bit of showers largely confined to areas along/east of the Mississippi River. These showers will move out of the area at or around sunset today, leaving us with dry conditions through the remainder of the weekend. Cloud cover will continue to decrease through the evening and night, with temperatures dropping into the low 60s. Weak ridging over the central CONUS will slowly shift east through the day Sunday, with a surface high pressure passing north of the area and toward the Great Lakes Region. A beautiful day will result, with a mix of clouds/sun, lighter northeast winds, and temperatures around 80. Enjoy the beautiful end to the weekend!

LONG TERM /MONDAY THROUGH FRIDAY/

Issued at 219 PM CDT Sat Aug 1 2026

The aforementioned ridge will continue to build and slowly track east towards the Great Lakes Region Monday and Tuesday. This will bring a period of quiet and dry weather through the start of the week, with seasonal temperatures and light winds.

Tuesday night and Wednesday, we will see this upper ridge break down with a wave pushing southeast towards the area, flattening the ridge. The wave will pass through the area Wednesday. Moisture will be a little slow to get here, with best warm advection moving into the area later in the night Tuesday. This may limit precipitation chances to Wednesday, when we see the best forcing and moisture pooling along the approaching boundary. While there are some subtle differences in timing, most global models favor precipitation onset in our northwest Wednesday morning and the boundary slowly working southeast through the day Wednesday. As of right now, there is much uncertainty regarding the chance for strong to severe storms. Instability will be marginal, but we might have sufficient shear for some organized convection Wednesday afternoon/evening. Although, confidence is low. Will continue to monitor and update.

After the midweek system passes, we will remain on the southern end of a broad upper trof over central North America. This pattern will keep us under the path of weak shortwaves passing along the flow of the upper trof. Thus, we will continue to see near-daily Slight- Chance PoPs through late week and into the weekend, especially with a baroclinic zone developing over the region. Guidance favors stronger southwest flow in the llvls under this pattern, which will allow for temperatures and humidity to increase during this timeframe.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1210 PM CDT Sat Aug 1 2026

Widespread MVFR to IFR conditions will continue for the next few hours, with conditions improving from northwest to southeast from 21-01z this afternoon/evening. Coverage and intensity of rain showers has dropped off quite a bit, resulting in vis remaining around 4/5 SM in the rain. All TAF sites should be clear of remnant rain showers by 00z. Otherwise, the main aviation concern will revolve around the cigs and gusty winds. Cigs have been gradually increasing over the last few hours, with most sites around/over 1000 ft now, except areas seeing showers. We will continue to see cigs lift through the afternoon, with all TAF sites seeing VFR cigs around 01z. We might see a resurgence of scattered-broken low clouds late tonight, after 10z, with MVFR/IFR cigs possible at some TAF sites.

Aside from low cigs, we have been dealing with gusty northeast winds around 25-30 KTs. After 00z this evening, we will see these winds decrease quite a bit, leaving most sites with northeast winds between 5-10 KTs for the remainder of the night.
